Photodetector ni igikoresho gihindura ibimenyetso byumucyo mubimenyetso byamashanyarazi. Muri Photodetector ya semiconductor, umutware wakozwe nifoto yishimiye ibyabaye fotone yinjira mumuzunguruko wo hanze munsi ya voltage ikoreshwa kandi ikora fotokore yapimye. Ndetse no mubisubizo ntarengwa, pin Photodiode irashobora kubyara gusa ibice bibiri bya elegitoroniki-umwobo kuri byinshi, ni igikoresho kidafite inyungu imbere. Kubisubizo byinshi, Photodiode ya avalanche (apd) irashobora gukoreshwa.
Ingaruka ya amplification ya apd kuri Photocurrent ishingiye ku ngaruka zo kugongana. Mubihe bimwe, electroni yihuta hamwe nu mwobo birashobora kubona imbaraga zihagije zo kugongana na lattike kugirango habeho ibice bishya bya electron-umwobo. Iyi nzira ni urunigi rwerekana, kuburyo ibice byombi bya elegitoroniki-byobo biterwa no kwinjiza urumuri bishobora kubyara umubare munini wa elegitoroniki-mwobo kandi bigakora ifoto nini ya kabiri. Kubwibyo, apd ifite ubushake buke ninyungu zimbere, zitezimbere igipimo cy-urusaku rwibikoresho. apd izakoreshwa cyane cyane intera ndende cyangwa ntoya ya optique ya fibre itumanaho hamwe nizindi mbogamizi ku mbaraga za optique yakiriwe. Kugeza ubu, abahanga benshi mubikoresho bya optique bafite ibyiringiro cyane kubyerekeranye na apd.
Rofea yigenga yateje imbere Photodetector ihuriweho na fotodiode hamwe n urusaku ruke rw urusaku rwongera urusaku, mugihe itanga ibicuruzwa bitandukanye, kubakoresha ubushakashatsi bwa siyanse Gutanga serivise nziza yo gutunganya ibicuruzwa, ubufasha bwa tekiniki kandi byoroshye nyuma yo kugurisha. Ibicuruzwa biriho ubu birimo: analog signal yerekana fotodetekeri hamwe na amplification, kunguka fotodetekeri ishobora guhinduka, fotodeteri yihuta cyane, icyuma cyisoko rya shelegi (APD), icyuma gipima, nibindi.
